You will learn more if you watch the movie first and write down your own thoughts before reading mine, so you can compare.
Moana is better than Frozen but has some nasty stuff about identity ("who you are"), emotions, and not needing skill. Also, like Frozen, it doesn't have a serious evil bad guy. I don't think Disney wants to admit there's evil in the world anymore. There's no character anything like Scar from The Lion King or Jafar from Aladdin. Not even close.
Moana starts when she’s like 2yo and her dad disrupts her important activity, without knowing what she was doing or why, and ignores her protests. he drags her away from the magic powers, wonderland, etc. then he says she will grow up to be chief but first she needs to learn “where she belongs”. learn your place, don’t go to the ocean!
then it glorifies primitive life. “the island gives us what we need” (they should try watching the Alone TV show to see how realistic that is). primitive island tribe life seems to consist of way more dancing than manual labor. and "we share everything we make" is so anti-Objectivist and collectivist.
moana sings (paraphrasing): i try to be the perfect daughter, but no matter how hard i try i still disobey (b/c my dad is wrong)
moana's world sucks because her people forget their identity. but she magically suspected it from birth and has a quick little magic shamanic journey to find out.
moana goes out, alone, to face the scary unknown on the ocean without bothering to even learn how to sail a boat first. b/c her heart told her to.
Moana has a strong and powerful male lead so that's an improvement over Frozen. the man and the woman have to work together, using both of their different strengths, to succeed. it's not great or anything. but that tradition is way better than the modern radical attack on it for the purpose of destruction. it's hard to reform anything when it's under attack by enemies. i'm not an enemy of our culture's traditions, just a would-be reformer. i'd much rather have people stick to old ideas than make things worse. i try to make sure my criticism of society isn't aligned with radical leftist and SJW agendas. i try to clearly separate myself from them and point out how they are worse than the traditional aspects of society which i criticize.
Moana go now
Moana don't stall
Don't worry 'bout how
Just answer the call of the sea
Not worrying about how, just proceeding, is stupid. Moana at least does some training after she's on her journey.
The overall meaning of the movie is as follows (notice this is basically good):
Society is stagnating and failing. It can't go on without any change. But it resists change. Moana is young and naive and willing to think outside the box. Her dad tells her to stop, but she does it anyway.
Change is scary, but Moana chooses to be heroic. She has setbacks and doubts, but keeps trying. It's hard, but she doesn't expect to be pampered. She isn't looking for a stress-free life on easy street. She succeeds at harnessing the power of the scary unknown and brings it back to her society which begins a new era of flourishing. By courageously facing and solving scary problems, Moana was a pioneer, and her individual actions changed the world while the bulk of her society did nothing.
For points of comparison, I'll summarize three more Disney movies. BTW, thanks to Jordan Peterson for his analysis of Lion King and Pinocchio which is great.
Lion King is about the danger to society from evil, and how heroic actions can defeat evil. Simba's father dies because society is blind to its evil side. Simba spends the middle of the movie being irresponsible, but then he realizes his error and decides to do better. Part of why he reforms is that he disappointed the girl. He's also aided by a shamanic journey, which basically means he does some introspection. Facing Scar is a stressful challenge, but Simba is able to succeed. This is pretty good.
Pinocchio is about a young boy growing up. He receives a lecture on morality which doesn't make any sense, because society is terrible at explaining morality logically, so that's a typical experience of children. Then he goes along with temptation which offers him rewards (fame and money) without the effort of education, even though his conscience (Jiminy Cricket) warns him. Pinocchio is generally passive and irresponsible, rather than taking charge of his own life. He gets a second chance and pursues temptation again (the easy fun of Pleasure Island). The excuse used is that he's sick and instant gratification will cure him. Pinocchio manages to escape before losing his humanity, but still has to face a difficult challenge (the whale) to put his life back together. He finally acts responsibly and heroically, and succeeds. This is pretty good.
In Frozen, Elsa nearly kills her sister Anna by not keeping herself under control. The danger is real. Nevertheless, the lesson she learns later is to "Let It Go", stop trying to control herself, and embrace her wild whims and arbitrary emotions. This doesn't make sense.
Anna is a contradictory mix of traits. She's helpless and feminine at times, strong and competent at other times. This fits with the modern lie that girls can be just like boys when they want, but also still be girls when they want. (Life roles don't just arbitrarily mix and match like that. It's hard enough to manage one lifestyle you focus on. Changing lifestyles like masks, at a moment's convenience, is ridiculous. It basically implies that everything people do in life is superficial and simple.)
Anna's love interest is a weak beta male with little to offer.
The theme of the movie is following your emotions. Very bad movie.
